Description

Device for leveling height of small instrument in narrow space Technical Field The utility model relates to the technical field of small instrument leveling, in particular to a device for leveling the height of a small instrument in a narrow space. Background At present, in the dry image testing process, the situation of uneven left and right of a vibration feeder can occur, so that materials can fall down along one side of the feeding groove, and the thickness of each small instrument or small mechanical equipment required to be heightened in the production process is unknown. The conventional leveling treatment method is to level the lower end of a small instrument by using a filler, such as copper foil leveling and leveling gasket leveling, but the method is not suitable for filling beyond a certain thickness, and the production efficiency is low because the filler has different thickness, so that the filling needs to be lifted each time and then fastened for testing. Although there are many similar height-adjusting products such as small lifting platforms in the market, the size of the height-adjusting platform is generally larger, the height-adjusting platform cannot be installed in a small space of a small instrument or small mechanical equipment, or the height-adjusting platform has insufficient fastening performance and insufficient bearing capacity, so that in summary, a set of height-adjusting devices with certain bearing capacity and fastening performance are designed in the small space of the small instrument or small mechanical equipment. Disclosure of utility model The utility model aims to solve the problems in the background art, and further provides a device for leveling the height of a small instrument in a narrow space. The technical scheme adopted for solving the technical problems is as follows: A device for leveling the height of a small instrument in a narrow space comprises a base, a first through hole, a limiting table, a second through hole, a limiting groove, a height adjusting nut, a lifting stud, a third through hole, a mounting bolt, a key slot, a limiting bolt, a locking nut and a fastener, The first through hole is formed in the base; The limiting table is welded on the base, and is provided with a limiting groove and a second through hole which is equal to the first through hole in diameter and is vertically and oppositely distributed; the heightening nut is matched with the limit groove and is contacted with the inner wall of the limit table; The lifting stud sequentially passes through the first through hole and the second through hole and is in threaded connection with the height-adjusting nut, and a third through hole with a narrow upper part and a wide lower part is formed in the lifting stud; the mounting bolt penetrates through the third through hole to be connected with the ground leg of the small instrument; the key groove is arranged on the lifting stud along the height direction; the two limit bolts respectively penetrate through the limit table and the base and are matched with the key grooves to limit the horizontal freedom degree of the lifting stud; The locking nut is in threaded connection with one end of the lifting stud; the fasteners are arranged on the base and are connected with the machine table surface of the small instrument. Further, a plurality of auxiliary rotating holes are formed in the circumference of the heightening nut, and one auxiliary rotating hole is matched with the steel nail or the steel roller. Further, a plurality of auxiliary threaded holes are formed in the base, fastening screws are adopted for fastening the fasteners, and the fastening screws penetrate through the auxiliary threaded holes to be connected with the table top of the small instrument. Further, the thickness of the height-adjusting nut and the groove width of the limiting groove can be adjusted to further reduce the height so as to adapt to smaller space. Furthermore, a plurality of anti-skid grooves are formed in the circumference of the outer walls of the height-adjusting nut and the locking nut. Compared with the prior art, the utility model has the beneficial effects that: Compared with the prior art, the height-adjustable device can conveniently adjust the height of a small instrument or mechanical equipment so as to avoid uneven phenomenon, has certain bearing capacity and fastening performance, does not need to repeatedly install fillers and test after fastening, has obviously improved height-adjusting effect, small occupied area, is suitable for height leveling operation in a narrow space, and has better use effect.
